Materials corrupted help

I’m using UE5 in the ss but I have the project in 4.26 too and it does the same thing. my materials keep getting corrupted, when I dive deep into parent materials and find the root material, it says those errors and I have no clue how to fix it. The material shown here is the root head material for metahumans, but this has been happening to so many of my other asset’s materials too. The material wont show when I launch it on my ios device. please help
